Background technology
Leaf mustard is a kind of crucifer, leaf mustard rich in nutritive value, and every 100 grams of edible parts, containing protein 1.9mg, crude fibre 1.7g, calcium 60mg, phosphorus 51mg, iron 0.9mg, also contain volatility particular matter.Taste delicate fragrance, matter are sweet crisp, are delicious foods that is cold and dressed with sauce, that to propagandize hotly etc.
Record according to Compendium of Materia Medica, leaf mustard has improve visual and auditory acuity, the function of sharp nine orifices, and modern pharmacological research shows that leaf mustard has effect that is hypotensive, reducing blood lipid.Because their root, stem, leaf and seed can be worked as medicinal, therefore there is the title of " medicine in kitchen ", " medicine celery ".Because the calcium phosphorus content of leaf mustard is higher, so it has certain calm effect with protecting blood vessel, bone can be strengthened again, preventing child osteomalacia.Leaf mustard is unique effect in body-care, has stomach invigorating, diuresis, clean blood, menstruation regulating, step-down, calmness, the effect such as anti-oxidant, anticancer, antibacterial.Leaf mustard has certain pharmacology and food therapy value, be more and more subject to liking of people, but Problems existing is the same with other vegetables, is difficult to long-term storage as the vegetables with nutritive value and health-care effect.On the one hand, when the time is longer, moisture evaporates, and interior void, eats mouthfeel poor; On the other hand, easily go mouldy, cause denaturalization phenomenon.In addition traditional pickled technique often causes the loss of leaf mustard nutritional labeling and desalinization wastewater to the pollution of environment.Therefore, development a kind of holding time is long, does not destroy nutritive value, meanwhile, can also keep its original local flavor, mouthfeel is good, acid is strong, leaf mustard processing method that environmental pollution is light has important practical significance.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of preparation method of rehydration seasoning dry mustard is provided, at utmost remain leaf mustard nutritional labeling, the production of seasoning dry mustard does not affect by seasonal, and traditional pickled technique can be avoided to cause the loss of nutritional labeling and desalinization wastewater to the pollution problem of environment; Make seasoning dry mustard not easily go mouldy and denaturalization phenomenon, instant, mouthfeel and local flavor sweet fresh, acid is strong, refrigerant tasty and refreshing, have chewiness, energy Appetizing spleen-tonifying, whets the appetite, have certain health-care effect, low-salt low-sugar, do not add any anticorrisive agent, the shelf-life is longer.
To achieve these goals, the present invention adopts following technical scheme:
A preparation method for rehydration seasoning dry mustard, comprises the following steps:
(1) select: select fresh, without disease and pest, atraumatic leaf mustard, cut leafage, fibrous root and root of the tail;
(2) cleaning is arranged: with the hot water of 40-60 DEG C, leaf mustard is rinsed well, then cool with clear water;
(3) cutting: the filament shape clean leaf mustard being cut into by knife 1.5 ~ 2mm, in the airing of ventilation area without shade, and regular turnover, dry rear obtained dry mustard, for subsequent use;
(4) rehydration: the dry mustard obtained by step (3), stainless cylinder of steel is put into after weighing, add running water, the weight ratio of dry mustard and running water is 1: 10, at ambient temperature, soak 2 ~ 8 hours, reach water suction full, chew clear-cut state, then take out, dewater with dewaterer;
(5) seasoning: drop in agitator tank after the dry mustard that step (4) is obtained is weighed, add flavoring, mixing and stirring simultaneously; The part by weight that described flavoring accounts for dry mustard is: monosodium glutamate 0.3 ~ 1.0%, peppermint oil 0.01 ~ 0.1%, ascorbic acid 0.2 ~ 0.3%, salt 1 ~ 2%, protein sugar 0.005 ~ 0.01%, peanut oil 2%, light-coloured vinegar 0.1 ~ 0.2%, pepper corn 0.2 ~ 0.8%;
(6) vacuum packaging: dry mustard step (5) seasoning mixed thoroughly loads in packaging bag, carries out vacuum packaging under 0.09MPa;
(7) isothermal holding: steam insulation 4 ~ 6h step (6) packaged product being put into 45 ~ 55 DEG C;
(8) sterilization: the seasoning dry mustard of step (7) is carried out pasteurize, is cooled to rapidly room temperature and is finished product after sterilization.
Preferably, the sealing of the packaging described in step (6) adopts the mode of the additional heat-sealing of sealed bag.
Preferably, flavoring described in step (5) accounts for the part by weight of dry mustard and is: monosodium glutamate 0.7%, peppermint oil 0.1%, ascorbic acid 0.25%, salt 2%, protein sugar 0.005%, peanut oil 2%, light-coloured vinegar 0.15%, pepper corn are 0.5%.
Preferably, steam step (6) packaged product being put into 50 DEG C described in step (7) is incubated 5h.
Compared with the prior art, beneficial effect of the present invention is as follows:
(1) preparation method of rehydration seasoning dry mustard of the present invention, leaf mustard nutritional labeling is at utmost remained in manufacturing process, and the production of seasoning dry mustard does not affect by seasonal, traditional pickled technique can be avoided to cause the loss of nutritional labeling and desalinization wastewater to the pollution problem of environment; The seasoning dry mustard utilizing preparation method of the present invention to process not easily goes mouldy and denaturalization phenomenon, instant, mouthfeel and local flavor sweet fresh, acid is strong, refrigerant tasty and refreshing, have chewiness, energy Appetizing spleen-tonifying, whets the appetite, there is certain health-care effect, low-salt low-sugar, do not add any anticorrisive agent, the shelf-life is longer.
(2) preparation method of rehydration seasoning dry mustard of the present invention, in the flavoring added, rationally arranges the proportioning of monosodium glutamate, peppermint oil, ascorbic acid, salt, protein sugar and light-coloured vinegar, effectively improve the quality of dry mustard during seasoning; Monosodium glutamate can make the glutamic acid carbon dioxide removal enzyme effect in itself and leaf mustard generate a large amount of GABAs (GABA), and the sweet delicate flavour of the dry mustard of production is increased; Peppermint oil add the acid that can strengthen dry mustard, there is synergistic function, refrigerant good to eat, and there is sterilization and anticorrosion effect; Adding in right amount of ascorbic acid can make the activity of myrosinase significantly improve, and acid strengthens, and can prevent goods generation oxidizing brown stain; Salt makes the activity of myrosinase improve, and the acid of leaf mustard silk strengthens, but addition is unsuitable too many; Protein sugar can not strengthen the acid of leaf mustard silk, but the sweet taste of leaf mustard silk can be made to increase; Light-coloured vinegar is small to the acid improving leaf mustard silk, but to the sense of taste, stablize acid and anticorrosion guarantee the quality favourable.
(3) preparation method of rehydration seasoning dry mustard of the present invention, packaged product is put into the steam insulation 4 ~ 6h of 45 ~ 55 DEG C, can effectively improve dry mustard alpha-aminobutyric acid content, sweet delicate flavour increases, leaf mustard glycosides simultaneously in leaf mustard is under the catalysis of thioglucose enzyme, the amount that hydrolysis produces propenyl mustard oil increases, and its acid strengthens; And temperature retention time, the power of holding temperature on dry mustard acid have impact, temperature should not too high, the time should not be too short.
